Web Usability in Academic Libraries: The Next Step

Abstract:

The advent of web technology significantly effected information organization and retrieval. The manner in which documents are arranged, labeled, and presented on the Web (the site's "information architecture") can have a major influence on how users effectively navigate Web sites and accurately access information. Past research recommends that implementation of proper usability guidelines/policies/standards (GPSs) contributes to user satisfaction and thus strongly affects a Web site's success.

The researchers collected data on usability GPSs, testing, staffing, and oversight from members of the Association of Research Libraries (ARL) with a survey instrument. The initial results indicate a strong agreement in the importance of Web usability; the data also reveals difficulties with developing, implementing, and maintaining GPSs; getting content-creators to follow GPSs; and the limited resources, including staffing, training, and time.

Geographic Information Resources on the Web: toward an effective use in academia

Abstract:

This research proposal describes a pilot study focused on geographic information and knowledge needs of academicians at the State University of New York, the University at Albany. The information will be obtained through a pilot structured interview and online survey of professors from different schools and departments. Additional information will be collected from secondary data sources. It is hypothesized that faculty from different occupations have differing knowledge, need and use of Geographic Information Resources (GIResources) available on the web. This study aims to identify relationships between occupation and level of awareness and use of available GIResources for research, teaching and personal use. Additional hypotheses target the need for increased information and training sessions organized throughout the various schools and departments at the university. The aim is to raise awareness about Geographic Information System (GIS) capabilities and increasing online resources available to help the teaching, research, as well as planning and decision making processes.

Spoils of War, Shapers of Policy: Archives as Cultural Heritage, the Case for an Internationally-Respected Protection Policy, and the Special Role for IT

Abstract:

Given the tragedies and failures in human history and current events, it is critical for humanity's survival and success to preserve its collective memory. Collective memory is knowledge that is gained through experience, constructed by society (in whole or in part), deemed historically valuable, and retained to be shared over time. Archives are the storehouses for collective memory. Archives are the materials created or received by an entity in the conduct of its affairs and preserved because of the enduring research, evidential, or informational value contained in the material. Archives serve as evidence of the functions and responsibilities of the materials' creator. To protect the world's archives is to preserve our collective memory, thus allowing us to learn from and hold ourselves accountable for our actions. This doable and critical endeavor is not being carried out in modern society. Indeed historically, archives tend to be the first, certainly the eventual casualties of armed conflict or spoils of war. George Orwell presented the gravity of the situation in 1984: "Who controls the past, controls the future: who controls the present, controls the past...Past events, it is argued, have no objective existence, but survive only in written records and in human memories. The past is whatever the records and the memories agree upon." This poster discusses the crisis -- one that human beings continually create for themselves -- and possible solutions built upon existing agreements that are international in scope and information technology being used in analogous applications.

Issues and Challenges in Conducting Cross-National E- Government Comparative Research

Abstract:

The International Research Program in Cross-boundary Information Sharing is a program that focuses on building new knowledge about cross-boundary information sharing in an international context. However, there are a few barriers that may impede the success of this effort. The comparative nature is one of the most substantial barriers that should be constantly considered to ensure successful outcomes.

This research addresses the challenges that Cross-National E-government researchers encounter while conducting comparative research in this area. The research explores the literature of e-government and other related domains to figure out these challenges. Then, these challenges are used as a framework to analyze how researchers in the area have dealt with these challenges, and to what extent the quality might be affected by ignoring any of these challenges as they described in the literature of the related domains.

Social Engineering Email Attack Strategies: Identifying an Overlooked Risk

Abstract:

Social engineering continues to be an increasing attack vector for the propagation of malicious programs via email. This poster investigates the major attack strategies employed by email worms that challenge current preventive and detective mechanisms. Malware incidents reported from 2000-2007 are analyzed. Our analysis shows that there has been a significant increase in the number of social engineering email incidents reported since 2000. The findings of our study show that the majority of social engineering email worms currently active were discovered back in 2004/2005. This testifies to the longstanding lack of basic protection on many computers. One of the fundamental concepts of security is to identify risk and mitigate its effects. The poster identifies a high risk group of Internet users, viz. residential broadband internet users. Organizations cannot neglect the tremendous threats that exist to their networks from compromised residential computers. The poster emphasizes the need for organizations, government and end users to work together to make the Internet a safer place.

The Resolution for the Problem of Lack of Transportation in Columbia-Greene County

Abstract:

The poster is about the problem of lack of transportation in Columbia-Greene County. The responsibilities of the Mental Health Association (MHA) of Columbia-Greene Counties include helping unemployed people to get jobs, with a focus on individuals with disabilities. During their work, they find that transportation issues often pose major barriers for their clients to obtain employment.

In 2007 the MHA served approximately 275 clients, 95% of whom did not own their own vehicles. The majority of these unemployed people live in rural areas that lack public transportation, which further complicates the task of getting to the work place. The MHA usually search jobs for clients within a range of 50 miles, and sometimes they have to encourage people to move for the work.

Investigation about the current transportation resources around Columbia-Greene County, an investigation questionnaire, and research on some possible resolutions for the problem will be included in the poster presentation.

Barriers to Socio-economic Opportunities in Africa: An e-Government Perspective

Abstract:

E-Government is not only a programmatic tool for offering government services effectively but also a participatory tool for citizens to get actively involved into government. Various non-government organizations (NGOs) attempt to evaluate e-Government initiatives through the combination of indices that heavily rely upon the level of information and communication technologies (ICTs) deployment. As a result of United Nations’ longitudinal evaluation of e-Government initiatives for more than 191 member states, e-Government has been identified as a medium to offer better socio-economic opportunities for citizens. However, other than technology related factors, there seems to be a range of other factors which significantly affect the rate of generating socio-economic opportunities through e-Government initiatives all around the world.

Using grounded theory approach, this research attempts to identify a comprehensive set of factors that are intimately associated with the success of offering better socio-economic opportunities, in the context of e-Government initiatives offered by governments in Africa. This study builds a new theoretical framework by comparatively analyzing 40 scholarly publications in the areas related to ‘socio-economic opportunities in Africa and e-Government’. The theoretical framework resulted by combining inductive and deductive approaches is expected to establish connections between socio-economic opportunities offered through e- Government and various influential factors categorized into political, social welfare, economic, and ICTs related domains. The proposed framework would be helpful in devising better metrics for measuring e-Government initiatives.

Query Refinement and Optimization for a generic natural language interface

Abstract:

In this poster, we are intended to seek an effective approach to refine and optimize the query of natural language, using a natural language interface. This work is based on a generic natural language interface for an XML database - NaLIX (Li 2005; 2006a). NaLIX can accept an English language to be a query input from users. This query is translated into an XQuery expression and then obtains results. The previous work has proved that such a system is able to process complex database queries in plain English. However, due to the limitations of the system, when a query is complex enough to input, it might be reformulated according to the system’s feedback so as to apply to NaLIX. Undoubtedly, it will increase the difficulty of retrieving or searching. Generally, in query refinements approaches, a user inputs a search query and then is shown search results plus or modifying possible new search queries. New search results will replace the current results. The goal of refining queries is to encourage users who are not satisfied with the search results to query again rather than quit searching task. In our study, we assume that queries after refining and optimizing are more effective than original queries. We are doing a pilot study to verify our assumption, whose results prove that approaches of query refinement for NaLIX are feasible and effective. In future work, if possible, we will continue to conduct two groups of experiments to further improve our assumption.

Tracking Patient Status with Adjective Information

Abstract:

The purpose of this project is to use NLP to analyze patients’ medical discharge summaries. This project comprises five stages: 1. Locate the information that marks the status of various entities, e.g., patient’s overall health, medications and their dosages, test results, etc. 2 Relate the status information to associated entities such as [patient]-[afebrile], [aspirin]-[500mg], [distress]-[acute]. 3. Build up relations between [entity]-[status] pairs such as {[distress]-[acute]}-{[aspirin]-[500mg]} (i.e., use 500mg of aspirin as medication for acute distress), where the identification of the relation is not trivial. 4. Generate a temporal model based on previous results showing the change in status over time. 5. Summarize all extracted information, based on the [entity]-[status] pairs, their inter-relations, and temporal information.

In the poster I discuss an overview of our project, highlight the proof-of-concept accomplishments to date, and present future work. We are currently in the process of identifying types of adjectives that bear status information. I hypothesize that the so-called “non-predicating adjectives” is status-bearing. Manually tagged medical discharge summaries using this type of adjective confirm this hypothesis.
